SORTlNG-DRUM FOR REMOVING KNOTS FROM DISSOLVED CELLULOSE.

srnorrrcarroiv forming m of- Letters Patent No. 547,600, dated October e. 1895.

Application filed Mach '1, 1895.-

To all whom it may concern:

Be it known that I, LUDWIG ENGEIMAYER, a subject of the Emperor of Germany, residing at Aschaffenburg, Bavaria, Germany, have in.- vented certain new and usefullmprovements in Sorting-Drums for Removing Knots from Dissolved Cellulose, of which the following is a specification.

The present invention consists of a sortingdru m for removing the knotsand coarser parts from dissolved cellulose, said sorting-drum being not only caused to rotate, but having also a shaking or bumping movement. The shaking or bumping motion is imparted to'the drum by means of a shaking-wheel mounted on the main driving-shaft and acting on suitable levers adapted to raise and lower one end of. the drum.

In order that the present invention may be more easily intelligible, reference is had to the accompanying drawings, in which similar letters denote similar parts throughout the several-views.

Figure 1 is a side elevation,

Fig. '2 a plan, and Fig. 3 an end elevation,

of an apparatus constructed according to the present invention.

In the apparatus shown two drums A A are I mounted in a vat-like framing B, said drums having their front ends partly closed by covers I), having flanged mouths (1, bearing in corresponding depressions of a cross-bar n, Fig. 3, mounted at the front of the frame, as hereinafter more particularly described. At the rear end the said drums are supported by their shafts f f, attached in said drum ends by means of skeleton frames in the usual manner and running in bearings g g at the rear of the frame, Fig. 2. Each of these shafts carries a bevel h, which engages in a corresponding bevel h on the main driving shaft '11, mountedat the rear of the frame B and extending across the same at rightanf gles to the shafts of the drums. The said driving-shaft carries suitable driving-pulleys,- and also at each end a shaking-wheel K K, which playson the end of the lever m, pivoted at each side of the frame at m and ppor at its front end the traverse 72, carrying the front ends of the drums A A. The said traverse or cross-bar n is further provided with springs o 0, arranged beneath said bar and resting on brackets 10 10, fast on the frame 13. The cellulose is introduced into the periname to this specification in the forated drums A at c and passes through the strains. 540,811. (No model.)

perforations, falling into the receptacle B, whence it may be removed through the opening '0, Fig. 1. It will be obvious that when the shaft 'i is rotated not only will the drums A A be set in a rotary motion, but the same will also receive an up-and-down shaking motion, imparted to them by the shakingwheels K K acting on the levers mm, which in their turn act to raise and lower the front ends of the drums by means of the cross-bar 'n, to which said pivot-levers are connected.

I wish it to be clearly understood that I do not confine myself to any particular number of drums, reserving to myself the right of employing more than two,.or, if desired, only one of such drums.

1 I claim as my invention- 1. The combination with a suitable receptacle, a perforated cellulose sorting drum mounted therein and means for rotating the same, of a cross bar supporting the front end of said drum, toothed wheels mounted on a transverse shaft at the rear of said drum and levers m pivoted to'the frame of the receptacle, connected at their front ends to said cross bar and at their free ends co-operating with said toothed wheels, substantially as set forth.

. 2. The combination of horizontally mounted rotary drums A and "means to rotate same, a cross bar to supportthe front ends of said drums as specified, lateral leversm m pivoted to the drum-containing receptacle and supporting said cross bar, a driving shaft z, having shaking wheels K K to operate the free ends of said levers 'm m in the manner and for the purpose substantially as described.

13. The combination of horizontally mounted rotary drums A and means to rotate same, a cross" bar-to support the front ends of said drums as specified lateral levers m m pivoted ,to the drum containing 7 receptacle, and s up porting said cross bar, springs o 0 under said cross bar, brackets 10 p to support said springs, a driving shaft 'i having shaking wheels K K to operate the free ends of said levers m m in the manner and for the purpose substantially as described.

In testimony whereof I have signed my presence of two subscribing witnesses.

I LUDWIG ENGELMAYER.
